Dominic hummed in approval, opening his mouth to invite the kiss to deepen as he continued to roll his hips and thrust into Onyx’s hand. The firmer strokes had his release building quickly, and he’d already been so close to the edge that it didn’t take long for him to come at all. He groaned against Onyx’s mouth, the feeling of the younger witch’s hand around him the next best thing to the tight clench of his hole.
Had anyone suggested when he’d first acquired the Rayne witch that at some future point in time Onyx would be willingly in his bed and stroking his cock, he’d have found the claim to be the utmost of absurdity. Yet here they were, with his fiery tiger taking step after step closer into Dominic’s webs, each action bringing him closer to the place where he would be Dominic’s pampered pet.
Writhing and moaning on his cock in bed, and feral and wild to anyone outside of it.
Perfection.
“Thank you,” Dominic murmured with a last kiss to Onyx’s lips before drawing away. “Go get rinsed off.”
Onyx withdrew from Dominic, nodding to him before getting quickly out of bed. He disappeared into the bathroom, and Dominic slid out of bed so he could begin getting ready for the day.
He dressed, then set out clothes for Onyx.
Clothes… and the small plug the Rayne witch would wear through his lessons.
Dominic left it there, going to his desk to begin checking his email as he waited for Onyx to return after his shower.
Onyx moved with his usual quick, casual gait as he approached the bed, only to freeze when he got close. “I can’t,” he whispered.
“Hmm?” Dominic asked, looking up from his laptop. “You can’t what?”
Onyx took a step back, like the plug was some kind of venomous snake that would leap up and bite him at any moment. “The plug,” he said unsteadily. “I don’t… think I can put that in me. I don’t think I can wear it.”
Rather than having Onyx come to him as he ordinarily did, Dominic got up from the desk and went to Onyx, holding his hand out when he reached the Rayne witch to bring him close. “Why can’t you wear it?” He lifted his hand to cup Onyx’s face.
Onyx had tensed up as Dominic approached, utterly stiff by the time Dominic drew him in close. “It’s too much." He quickly shook his head
“Lie down on the bed on your back,” Dominic instructed, voice still gentle, but firm. “I’ll put it inside you, you’ll get dressed and we’ll eat breakfast, and then evaluate.”
Onyx was trembling as he replied, “You said I had to wear it during my lessons, not before my lessons.”
Dominic nodded. “I did say that,” he agreed. “And after breakfast, I can take it back out again until your lessons are due to begin, but I want you to wear it now for breakfast. It will be more difficult to intercede if you have a poor reaction during the lesson than if you do now. After this, you need only wear it during the lessons.”
Swallowing hard, Onyx turned his head to stare at the plug. “You’re going to make it hurt,” he whispered.
“I will not make it hurt,” Dominic said softly. “I only want your pleasure, Onyx Rayne, not your pain. Your pain is in the past. I have given you my word on this, haven’t I?”
“It’s not going to be pleasure.” Onyx swallowed audibly as he stared beseechingly up at Dominic. “It’s not going to feel good. It’s going to be uncomfortable, even if it doesn’t hurt.”
“Lie back on the bed,” Dominic repeated, voice still soft despite the clear order. “Wear it through breakfast, and then we will evaluate how you feel.”
Onyx didn’t quite choke back a whine as he went to the bed. He lay down next to the plug with a miserable, dejected look on his face.
“Lift up your knees, feet on the bed,” Dominic instructed, taking a seat on the bed and reaching for the container of lube that had been left laying out. He picked up the plug and squirted some lube on it, slicking it up.
The steel plug was barely larger than two of his fingers, which Onyx had easily taken not even half an hour prior, so Dominic knew he should have no discomfort with it. It had been made for training purposes, intended to be easy to wear. It might be unusual, but not uncomfortable or painful.
Onyx bit his bottom lip but obeyed, getting into position even as he flinched at the sound of lube being squirted onto Dominic’s fingers. His eyes squeezed tightly closed.
“Finger first.” Dominic pressed a fingertip against Onyx’s hole before slipping it inside.
Even though Onyx had washed himself thoroughly in the shower, there were still the remnants of lube in the tight passage. Onyx’s hole was still relaxed from being fingered, though he clenched around the finger.
“Relax,” Dominic instructed. “Slow breaths in and out.” He warmed up the steel in his hand so that it wouldn’t be as cold when it first entered the younger witch’s body. “Second finger,” he warned before adding the second with little resistance, given how recently Onyx’s body had opened for him. He hardly had to scissor his fingers at all to get Onyx’s body to be loose enough for the plug. He withdrew his fingers and placed the tip of the plug against Onyx’s hole. “Plug.” He started to slowly press it in, working it in rather than trying to slide it in all at once. “Slight burn.”
“Are you going to make it bigger?” Onyx whispered, his eyes opening again as he stared at Dominic.
Dominic paused, plug partially inserted, brow furrowing. “Make it—? Oh, no. Only some metals can be manipulated magically that way. Steel isn’t one of them. I can’t make this one bigger, and I wouldn’t if I could. This one can’t be changed, I promise.”
